Enterprise Architecture Modelling, Visualizationand Analysis with ArchiMate and TOGAFHenk Jonkers22nd Enterprise Architecture Practitioners ConferenceLondon, April 28, 2009

What is Enterprise Architecture?A processWay of workingAimed at the development and use of enterprisearchitectures within an enterpriseWith people and resourcesA productA design that shows the coherence between products,processes, organisation, information supply andinfrastructure, based on a vision and certainexplicit starting points, principles and preferencesInformation architectureWith the objective of steering changes?Process architecture?Application architectureTechnical architecture?

Architecture according to ISO/IEC 42010TOGAF and ArchiMate both uses the architecture definitionfrom Standard ISO/IEC 42010:2007:An architecture describes:the fundamental organisation of a system, embodied in itscomponents, their relationships to each other and theenvironment;and the principles governing its design and evolution.Practically, an architecture is represented in architecturaldescriptions from the viewpoints corresponding to theconcerns of the stakeholders.

TOGAF ACF and ArchiMateThe ACF provides a global structure for architecture buildingblocks: it identifies the concepts needed in the different ADMphases.ArchiMate provides a well-defined language, includinggraphical notation, covering the core of the ACF.With ArchiMate, relations between different architecturaldomains can also be modelledArchiMate models form a basis for views, visualizations, andanalysisSome concepts from the ACF are still missing in ArchiMatepotential future extensions of the language
